3 Description

The LP5899-Q1 SPI-compatible connectivity enables

LP589x-Q1 device family to be controlled using

a standard SPI controller. The device features an

internal oscillator to generate the continuous clock

required by the LP589x-Q1 device family. Jitter can be

added to the continuous clock for EMI enhancement.

The transmitted data is aligned to the continuous

clock to maintain the timing requirements of the CCSI

interface.

LP5899-Q1 incorporates reporting of faults in both

the LP589x-Q1 daisy chain and LP5899-Q1 internal.

Data transmission of register and VSYNC commands

to the LP589x-Q1 daisy chain is CRC protected by

LP5899-Q1. In addition, the data line is guarded by

LP5899-Q1 for stuck-at faults.
